    Michael Buckstein, M.D., Ph.D. is a radiation oncologist specializing in the treatment of gastrointestinal tumors including the esophagus, stomach, pancreas, liver, gall bladder, bile ducts, rectum, and anus as well coronary brachytherapy.  He uses many advanced techniques such Intensity Modulated Radiation Therapy (IMRT), Image Guided Radiation Therapy (IGRT), Stereotactic Body Radiation Therapy (SBRT), and brachytherapy to maximize local control and cure of the cancer while minimizing radiation side effects to healthy tissue.

    Dr. Buckstein’s primary research focus is attempting to identify causes and limit treatment related toxicity from radiation therapy.  In addition to large retrospective reviews identifying factors involved in disease outcomes and toxicity, he is also heavily involved in projects using genomics to identify specific individuals at risk for developing adverse side effects from treatment. He was involved in a novel study identifying genetic factors predictive for the development of erectile dysfunction following radiation for prostate cancer.  His work has resulted in multiple presentations at international meetings as well publication in peer reviewed journals.

Use of Stereotactic Body Radiation Therapy and Hepatocellular Carcinomas

Dr. Buckstein is the principal investigator on a study using combination trans-arterial chemo embolization (TACE) with stereotactic body radiation therapy (SBRT) as a treatment paradigm for treating large hepatocellular carcinomas.  In addition, he is actively working to safely integrate SBRT into treatment paradigms for HCC.

Outcomes Based Research for Gastrointestinal Malignancies

Using a variety of tools institutional and national based databases, Dr. Buckstein is involved with research attempting to identify treatment related predictors for outcomes and development of treatment related toxicities. He has a particular focus on understanding outcomes with patients who have Inflammatory Bowel Disease who develop a malignancy. 

Identifying Genetic Predictors for Radiation Treatment Related Toxicity

Dr, Buckstein is involved in mutliple projects using Genome-Wide Association Studies (GWAS) to identify individual genetic differences that might predict for the development of radiation toxicity. This will ultimately allow physicians to personalize therapy to each individual, potentially minimizing toxicity and optimizing therpeutic outcomes.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Buckstein did not report having any of the following types of financial relationships with industry during 2014 and/or 2015: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.

Insurance Information

Physicians who provide services at hospitals and facilities in the Mount Sinai Health System might not participate in the same health plans as those Mount Sinai hospitals and facilities (even if the physicians are employed or contracted by those hospitals or facilities).

Information regarding insurance participation and billing by this physician may be found on this page, and can also be obtained by contacting this provider directly. Because physicians insurance participation can change, the insurance information on this page may not always be up-to-date. Please contact this physician directly to obtain the most up-to-date insurance information.

Insurance and health plan networks that the various Mount Sinai Health System hospitals and facilities participate in can be found on the Mount Sinai Health System website.
